How do I configure port forwarding on my TG862?

Port Forwarding allows the option to run a publicly accessible server on the LAN by specifying the mapping of TCP / UDP ports to a local device.  This enables incoming requests on specific port numbers to reach devices such as Web Servers, Mail Servers, and Digital Video Recorders (DVR).  This document describes how to create a port forwarding entry.

NOTE 1: It is recommended to manually configure the TCP / IP settings on the server that will be remotely accessible.  If this is done, then it is mandatory to configure the following settings:

  • IP address
  • Subnet mask
  • Default gateway
  • At least one DNS address

If the following settings are configured without the default gateway, remote access to the server will not be available, as it will only be accessible from the local network.

NOTE 2: When manually configuring the TCP / IP settings on a device, make sure that the DHCP pool in the TG862 doesn't include the IP address of the server.
